SICK OSCAR- picture

tiger oscar has grayish color and is just sitting on the bottom of the tank with what looks like little indentions on the top of his head

Need to know ammonia, nitrite, nitrate, pH, and assuming the fish are the ones in your sginature, how big is each fish?

about 6 inches each and the pH is 7.2 and ammonia, nitrite and nitrate are normal

i added a large snail yesterday if that has anything to do with it

By normal do you mean that the ammonia and nitrite are both ZERO? Sorry if it seems excessive, but i've seen too many people claim their ammonia/nitrite were fine when there was a reading.

I really have no clue what to tell you. Being pale and staying on the bottem can be very vauge, general symptoms. The indentations don't look like HITH or ulcers. Have you seen any scratching on objects, is he breathing fast, are the gills red and inflamed?

Adding an airstone may help him out, just to increase the oxygen he is getting.

Looks like a costia infection which is a parasite and could have been brought in with the snail. Hows the other fish doing? Have a look also at the gills to see if any damage has been done. Healthy gills are a cherry red colour.
The grey covering is the slime coat reacting to it and the parasite may be hard to get rid of.
Has the fish been scratching at all?

heres what i could find on treatment.

Treating mild to moderate outbreaks is fairly easy, usually requiring just one treatment. Most proprietary parasite treatments will work. My own preference is malachite and formalin, provided that fish are not suffering from gill damage. Prolonged immersion with potassium permanganate is another option but again this is not advisable if gill damage is suspected. When gill damage is suspected salt offers the safest route as either a bath treatment (20 - 25g/litre for 20 - 30 minutes) or as a long-term immersion at 3-5g/litre.

In advanced and severe cases, resolution may be very difficult because of the numbers of parasites involved, excess mucus and hyperplasia helping to protect the parasites from chemical treatments and the poor health of the fish. In such circumstance tank treatments with chloramine-T and long term salt support is the best option with treatments being repeated until the fish shows signs of improvement.

k thanks i bought some stuff today that is supposed to take care of it and there really hasnt been any scratching that ive noticed and the gills look okay but he does seem to be breathing a little heavier o and by the way tttnjfttt the levels are at 0

Does it look like he is covered in grey slime, or his color has just faded because of stress?

it is gray and the white parts are fuzzy

If the white parts are fuzzy it is a fungus. You need to treat with salt and lower the temp. This is the best way I know of to treat fungus. Which I am sure they are medicine for. I just never use medicine if I can get out of it. I keep my water clean and do weekly vac and I never have any problems. Oh and you need to do a water change also.

Unless the fuzz is appearing on an open wound, it is most likely columnaris, a bacterial infection that is often mis-diagnosed as "fungus".

Not the author of this.....

Columnaris (mouth rot, mouth fungus, 'flex')

Symptoms

Early signs of this disease are greyish-white marks or patches around the mouth, or on the body or fins of the fish. These may appear thread-like, particularly around the mouth, giving rise to the incorrect name of 'mouth fungus'. Fins will deteriorate and sores may appear on the body. The gills may be affected, giving rise to bacterial gill disease. It may cause 'shimmying' behaviour in fishes like livebearers.
Causes

The disease is caused by the bacteria Flavobacterium colmnare, formerly known as Flexibacter columnaris. It has been refered to as 'mouth fungus' (even though the cause is bacterial), due to the whitish strands which may appear fungus-like. These are Gram-negative, rod shaped bacteria, which move by gliding across a surface.

As with many bacterial diseases, poor water quality is a major factor in triggering the disease. Sudden changes in conditions may also trigger it, and the disease is common in newly imported fish.
Possible cures

Anti-bacterial medications should cure this disease if used promptly. At later stages, the bacteria may invade internal organs, in which case only antibiotics may be effective. Several strains exist which vary in their virulence (how 'aggressively' they cause disease)..
